FileInbound DSL: Add recursive for convenience (#3495)

Browse Source 
* FileInbound DSL: Add `recursive` for convenience

Related to https://stackoverflow.com/questions/66171881/how-to-read-nested-txt-file-from-spring-integration-file

The `FileInboundChannelAdapterSpec` can be configured with an external `DirectoryScanner`,
but it sometimes becomes burden for end-users to extract a scanner bean and configure it
with all the required file filters

* Expose a `recursive(boolean)` option for better end-user experience
* Rework `FileTests` for JUnit 5
* Mention a new option in the docs

* * Restore accidentally removed code
* Restore special symbols in the `FileTests`
* Fix language in the docs according review

For example, the `SimplePatternFileListFilter` filters out directories by default.
See https://docs.spring.io/spring-integration/api/org/springframework/integration/file/filters/AbstractDirectoryAwareFileListFilter.html[`AbstractDirectoryAwareFileListFilter`] and its implementations for more information.
NOTE: Starting with version 5.5, the `FileInboundChannelAdapterSpec` of the Java DSL has a convenient `recursive(boolean)` option to use a `RecursiveDirectoryScanner` in the target `FileReadingMessageSource` instead of the default one.

IMPORTANT: This means that existing keys in a persistent metadata store will not be found for files beneath the top level directory.
For this reason, the property is `false` by default; this may change in a future release.
The `FileInboundChannelAdapterSpec` has now a convenient `recursive(boolean)` option instead of requiring an explicit reference to the `RecursiveDirectoryScanner`.
